Process for producing K3H(SO4)2 crystals and potassium sulfate crystals |
| 摘要 |
A process for producing K2SO4 from potassium chloride salts, calcium sulfate salts and another sulfate source wherein syngenite is formed and then decomposed with mineral acid to produce crystalline K3H(SO4)2. The K3H(SO4)2 crystals are recrystallized to produce K2SO4 crystals.
